spring实战-混合装配bean

spring 还可以使用xml和JavaConfig进行混合装配Bean

TestMain

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes=ServiceConfig.class)
public class TestMain {

@Autowired
private Service service;

@Test
public void test(){
System.out.println(service.getConnection().getProxyInfo().getIp());
}
}

ServiceConfig

package com.halfworlders.web;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.ImportResource;

/**
 * 通过@ImportResource在JavaConfig中引入XML配置
 * 还可以通过@Import导入另外一个JavaConfig配置
 */
@Configuration
@ImportResource("classpath:spring-beans.xml")
public class ServiceConfig {

@Bean
public Service service(Connection connection) {
return new Service(connection);
}
}

ProxyInfoConfig

package com.halfworlders.web;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class ProxyInfoConfig {

@Bean
public ProxyInfo proxy() {
return new ProxyInfo();
}
}

spring-beans.xml

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"xmlns:p="http://www.springframework.org/schema/p" xmlns:c="http://www.springframework.org/schema/c"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context.xsd"><!-- 通过这种方式无法实现在XML中引入JavaConfig，如果有大神看到本帖，请告知原因 --><bean id="proxyInfoConfig" class="com.halfworlders.web.ProxyInfoConfig" /><bean id="proxyInfo" class="com.halfworlders.web.ProxyInfo" /><!-- 通过c命名空间装配构造函数参数 --><bean id="connection" class="com.halfworlders.web.Connection"c:_-ref="proxyInfo" /></beans>
